The amount of water vapor in the air
The mass of water vapor contained in a certain volume of air.
The percentage of water vapor in the air compared to the maximum amount the air could hold.
The temperature at which the water vapor in the air becomes saturated and condensation begins.
The pushing force of the atmosphere
A mass of sinking cool air that usually bring fair weather.
A mass of rising warm air that usually bring wet, stormy weather.
The movement of air caused by cool air over the ocean moving toward the land.
A wind that blows from the land to the sea due to local temperature and pressure differences
Cloud formation that occurs when warm moist air is forced to rise up the side of a mountain.
Facing toward the direction from which the wind is blowing. Cold and wet side of the mountain.
In the direction away from the wind. Hot and Dry side of the mountain.
A body of air that has about the same temperature and moisture throughout. It gets its name from the source region over which it formed.
The front of an advancing mass of colder air.
The front of an advancing mass of warmer air.
A warm front that's overtaken by a cold front.
When a warm air mass and a cold air mass meet and no movement occurs.
A sea or land breeze over a large region near India that changes direction with the seasons. Strong wind that brings heavy rain to southern Asia in the summer.
Microscopic particles on which water vapor condenses to form cloud droplets.
Large centers of low pressure that generally travel from west to east. It has a warm front with a cold front behind it.
Lifting of air resulting when cool air acts as a barrier over which warmer, lighter air will rise.
A high-speed high-altitude airstream blowing from west to east near the top of the troposphere.
Lake Effect Snow
Snow created when cold air flows over relatively warm water then over cold land.
A line on a weather map that joins places that have the same air pressure.
An instrument used to measure temperature.
An instrument that measures atmospheric pressure.
Instrument used to measure wind direction.
An instrument used to measure wind speed.
An instrument used to measure precipitation.
Instrument used to measure water vapor content of the atmosphere.
The temperature at which all molecular motion stops. 0 Kelvin
Formed when rain falls through a layer of freezing air.
Water falling in drops from vapor condensed in the atmosphere.
Rain that falls as liquid then freezes as it hits a surface.
Precipitation falling from clouds in the form of ice crystals.
